519.5.4 DDNSIf you are not planning on connecting to the network camera over a remote connection, butonly in your local network, you can skip this section.Dynamic DNS is a network service that provides the capability for a networked device, suchas a router or computer system, to notify a domain name server to change, in real time(ad-hoc) the active DNS configuration of its configured host names, addresses or otherinformation stored in DNS.In simpler terms: Users of private Internet services are often faced with a problem: The ISPtypically changes the IP address assigned to the user based on a time interval. This may beas often as once every 24 hours or as seldom as once every 30 days. For the average user thisis not a problem. However, if you want to be able to connect to the local camera (e.g., in yourhouse) from a remote location (e.g., the office), you need to know under which Internetaddress the camera can be reached. However, you don’t know what the current Internet IPaddress is. So you are beginning to see the problem.DDNS solves this problem by allowing you to create a domain name for your home network,which you can always use to access the camera. To use the DDNS function, you will need todo the following two things.First, create a DDNS hostname with a DDNS service providerSecondly, set up a DDNS client in the home network that contacts the DDNS service providerand updates the IP information.If the router in your home network is equipped with a DDNS client, we recommend using therouter instead of the camera. Most SOHO routers are equipped with a DDNS client and sincethe router is in direct control of handling the Internet connection, it’s the device best suited
